This walkthrough assumes that the player knows how to move the character around the locations and manipulate the various things required to complete each task (ie, you've completed the training section). The numbers in brackets are to show you how near you are to gaining an achievement & is something I've made up myself to keep track of the more annoying ones!

This is not a definitive solution, some of the puzzles can be completed in a different order and some can be completed in a completely different way. I have listed each interaction exactly how it looks at the top-right of the screen, if you see something different in this action description, then you're doing it wrong! I can't be held accountable for the results! This walkthrough is set out exactly how I did it, it does work! HONEST!
If you follow this walkthrough as it is you will get all 12 achievements in the correct order, however you will have experienced about 75% of the game and well under 50% of the conversations (256 on the leaderboard). You might want to play the game through on your own before consulting this walkthrough if you want to experience more of the game, and get a proper sense of achievement by solving the puzzles yourself. For the rest of you... here we go!

It is recommended that you save at the beginning of each Act, or at regular intervals. Whichever is easiest for you.

ok on ACT 3 on the last section as outlined above i didnt understand what the guide ment and sent the robot towards the cheese (thinking it would scare the bees off) and now the record player, robot and cheese are all on top of the hive and i cant continue!!! any ideas how to fix this as the game has saved itself!!

go upstairs and grab the lullaby record off of the turntable. Then, go downstairs to the basement. The giant bees are having a giant dance party down there. Gromit won't be able to walk past the end of the upended table without being chased out of the room. He needs to get to the party record on the turntable on top of the hive and shut this party down, but he can't do it without a substantial amount of protection. The Sniffer 3000 is sitting over on the table. You can summon it by selecting one of the cheeses in your inventory on the Sniffer's remote control. As it approaches you, the bees attack it, but their stings are useless against its metal frame. However, we can't steer it to where we want to go just yet. Head upstairs and exit the house. In the yard, walk over to the side of the house with a tall wooden gate. Walk through the gate to the side yard with an open coal door (next to the kitchen entrance). Drop one of your slices of cheese (let's go with Wensleydale this time, just for kicks) down next to the turntable, and then return to the basement. Once there, climb into the Sniffer 3000 by clicking on it, and select "Wensleydale" (or whichever cheese you dropped down next to the record player) on the remote control, and you'll cruise through the hive to the very top. Swap the dance record with the lullaby record; all the bees will doze off, and you can safely exit the hive and return upstairs. Go back into the kitchen and report the victory to Wallace. this is from http://www.telltalegames.com/wallace...fthebumblebees and not my work but explains it better

STUPID STUPID GLITCH!!!! Seems if u make this mistake you have to restart the entire game!!!

There is no glitch, you can save the game at any time; you don't have to start from the beginning if you make a mistake (eg, the lullaby record & record player in Act 3 is a little glitchy... I had problems myself when I was developing the walkthrough. The bee comes in from the trap-door after about a second, if you do not use the lullaby record within that time you will need to get the Gorgonzola to complete the Act! I thought the timing wouldn't be an issue as all the testers who went through this for me had no problems themselves).
Also, unlike Penny Arcade Adventures, you can save in different slots... so it's recommended saving at the beginning of each Act in one of the four available slots.

You all have to remember that this is ONLY an achievement walkthrough, it is NOT meant to be an achievement guide. If you only go through this walkthrough, you will not fully understand why you've unlocked these achievements, so any minor mistakes or deviations will be difficult to rectify. I hope someone will do a proper x360a guide over the next few days... it was NEVER my intention to do so. I just hope I've helped some of you to get 200GP in this amazing game and I look forward to helping you again when Episode 2 (The Last Resort) is released on XBLA!

Go to the police station in town and paw at the door.
The constable will give you some Gorgonzola.
Go back to the cellar and call the sniffer back using the Gorgonzola then climb into it and go up to the top of the hive.

You wont be able to get the "No Go Gorgonzola" achievement but you can pick that up next time you play through and I recommend playing through a couple of times anyway just for all the stuff you miss the first time round.
